In May 2016, BBC reporter Rupert Wingfield-Hayes was expelled from North
Korea for showing disrespect and 'distorting facts'. He now tells the
full story of his visit to the country and explores what his detention
and interrogation by senior Korean officials say about this secretive
state. He investigates the apparent upturn in the North Korean economy
and asks if the signs of improvement in the capital Pyongyang are real.
He also examines whether the people there are genuinely loyal to their
young leader or whether Kim Jong Un is ruling by reign of terror.
